Indianapolis, Ind. — The Indiana Utility Regulatory Commission (Commission) issued an order opening an investigation (Cause No. 44602) into Indianapolis Power and Light Company's (IPL) ongoing investment in, and operation and maintenance of, its network facilities.

Despite these discussions and efforts, IPL has experienced continued failures in its underground network facilities, resulting in a risk to public safety.

The Commission also will set a procedural schedule, which will include a field hearing where the Commission will take public comments.
